If a favorite coaster is on your must-ride list, 2026 is shaping up to be a year of goodbyes. Several well-known rides are either confirmed to run their last laps once the year wraps up or have already been pulled from operation months ahead of schedule, and the reasons range from park expansion plans to safety concerns to a park shutting its gates for good.
Here’s a rundown of the roller coasters closing after the 2026 season (or during it), why each one is actually going away, and how to plan a visit before it’s too late.
Quick Answer
The biggest confirmed closures tied to 2026 are Thunderation at Silver Dollar City in Branson, Missouri (its last day of operation is January 2, 2027, right after the park’s 2026 season), every ride at Wild Waves Theme Park near Seattle (the entire park closes for good after November 1, 2026), and X2 at Six Flags Magic Mountain, which was permanently retired in September 2026 after safety concerns rather than waiting out the season.
The Confirmed Closures
Thunderation, an Arrow Dynamics mine train coaster that opened at Silver Dollar City in 1993, closes permanently on January 2, 2027, after carrying guests through the park’s full 2026 season. Silver Dollar City built an in-park story around the closure, framing it as the Marvel Cave Mining Company reclaiming the land to resume mining — that’s themed storytelling the park created for the ride’s farewell, not an actual mining operation. The retirement comes as Silver Dollar City pushes ahead with its multi-year expansion. The park’s next coaster, Miner’s Mountain Express, a $150 million Mack Rides family coaster billed as the longest family coaster in the Midwest, opens in spring 2027 in a newly designated area called Daredevil Pass, alongside Wildfire and Powder Keg. Silver Dollar City has not described it as a replacement built on Thunderation’s site.
Wild Waves Theme Park, a Federal Way, Washington staple for nearly five decades, is closing entirely after the 2026 season, which runs through November 1. That takes every ride at the park down with it, including its coasters: Wild Thing, Klondike Gold Rusher, Timberhawk: Ride of Prey, and the park’s kiddie coaster. Park ownership, Premier Parks, cited rising operating costs and losses that never fully recovered after the pandemic-era shutdown as the reason for closing rather than continuing to operate at a loss.
X2 at Six Flags Magic Mountain is a different kind of closure. Built by Arrow Dynamics and opened in 2002 as the world’s first fourth-dimension coaster, X2 uses a traditional chain lift hill and is known for seats that rotate independently of the train, not for launches or spinning cars. The ride had not operated since July 2026. In August 2026 a CNN investigation reported that internal park records documented at least 70 head and neck injury complaints over a three-year span, and lawsuits over traumatic brain injuries followed. On September 29, 2026, Six Flags announced it would permanently close X2, saying the ride had consistently passed safety tests but that closing it was the right thing to do. X2 opened as X in 2002, was rebuilt as X2 in 2008, and carried more than 16 million riders.
Why Coasters Get Retired
Closures like these tend to fall into a few buckets. Some, like Thunderation, come down to a park’s own expansion and master-planning decisions rather than any problem with the ride itself. Others, like Wild Waves, happen because an entire park’s finances no longer pencil out, especially for seasonal, weather-dependent operations that took a hit during the pandemic and never fully bounced back. And some, like X2, are safety-driven: after enough incident reports, injury claims, or litigation, a park may decide retiring the ride outright is simpler and safer than continuing to operate or repair it.
Aging infrastructure is another recurring factor across the industry — older steel and wood coasters can become expensive to maintain as replacement parts get harder to source, which is part of why so many first-generation coasters from the 1970s through 1990s are gradually being phased out at parks nationwide.
Tips for Planning a Farewell Visit
If you want to ride one of these coasters before it’s gone, don’t wait for a published ‘last day’ to show up in a headline — check the park’s own website and social accounts for the official closing date and any farewell-event schedule, since these can shift. For Wild Waves specifically, remember the whole park is closing, not just the rides, so plan your trip before November 1, 2026, and expect crowds in the final weeks. Thunderation’s actual last day is January 2, 2027, so there’s a bit more runway than ‘end of the 2026 season’ might suggest.
A common mistake is taking a park’s themed farewell story at face value. Silver Dollar City’s ‘mining company reclaiming the land’ narrative for Thunderation is fun, in-universe theming, not a literal explanation — the real driver is the park’s publicly announced expansion, and the next coaster, Miner’s Mountain Express, opens in 2027 in the park’s new Daredevil Pass area rather than on Thunderation’s site.
If a ride has been pulled mid-season for safety reasons, like X2, check official park statements rather than rumor — reopening plans (or permanent retirement) are usually announced directly by the operator, not leaked in advance.

Roller coasters closing after 2026 FAQs
What roller coasters are closing after the 2026 season?
The most notable closures are Thunderation at Silver Dollar City, which runs through the 2026 season and permanently closes on January 2, 2027, and every coaster at Wild Waves Theme Park, which shuts down for good after November 1, 2026. X2 at Six Flags Magic Mountain was also permanently retired during 2026, though it closed mid-season rather than at year’s end.
Why is Thunderation closing at Silver Dollar City?
Silver Dollar City tells the closure as an in-park story about the Marvel Cave Mining Company reclaiming the land for mining. That is themed storytelling for the ride’s farewell, not a real mining operation. The practical context is the park’s ongoing expansion: its next coaster, Miner’s Mountain Express, opens in spring 2027 in the new Daredevil Pass area, and the park has not announced what, if anything, will take Thunderation’s spot.
Is Wild Waves Theme Park closing completely?
Yes. The entire park, including all of its rides and coasters, is closing for good after the 2026 season ends on November 1, 2026, due to operating losses that never fully recovered after the pandemic.
Can I still ride X2 at Six Flags Magic Mountain?
No. X2, a chain-lift fourth-dimension coaster built by Arrow Dynamics, closed in mid-July 2026 and was permanently retired by Six Flags in late September 2026 following a history of safety concerns and reported rider injuries; it will not reopen.
